Lily-of-the-valley Overview

Spironolactone Overview
-
Spironolactone is used to treat certain patients with hyperaldosteronism (the body produces too much aldosterone, a naturally occurring hormone); low potassium levels; heart failure; and in patients with edema (fluid retention) caused by various conditions, including liver, or kidney disease. It is also used alone or with other medications to treat high blood pressure. Spironolactone is in a class of medications called aldosterone receptor antagonists. It causes the kidneys to eliminate unneeded water and sodium from the body into the urine but reduces the loss of potassium from the body.
-
High blood pressure is a common condition and when not treated, can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs may cause heart disease, a heart attack, heart failure, stroke, kidney failure, loss of vision, and other problems. In addition to taking medication, making lifestyle changes will also help to control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising at least 30 minutes most days, not smoking, and using alcohol in moderation.
